If you receive a message stating: "Price has been changed due to different billing country than Newsstand", this indicates that the price of the publication varies depending upon the region, as decided by the publishers. Zinio does not have the flexibility to change the price of a publication, regional limitations are set by the publisher.
For zinio.com purchases, these restrictions are based upon the credit card billing address. Should you have a credit card billing address matching one of the authorised countries then you can enter these details to amend the pricing.
